The front end of rod (1 is provided "with a head (7" in whichan exlension rod) is adjustably mounted at rightvangies thereto, saidrixl'f-being rotatably and a set-screw gheing proi'ided'in said head (Zto hold the rod f in place A 'resnsupporting shank or arn'i. i2 ismounted in 'a head 7" at the lower end of the rod f, and

A heel-rest in the form of anangularly shaped head 7' is mounted on the end of arm 72, and, While itis usuall preferable'tojmount' it on the end of the arm at the left oftheoperator;

as he faces'the machine, a rerersal of 'the posltion oft-the parts wouldbe an obv ous Said head is formed to provide a heel-supporting face-y"on its upper side the rear edge j 'thereof. next the abrading face ofthe Wheel. extending. parallel to the arm h. The left-handside-edgefextend-s from.'

acute angle therefo. or obliquely to the right, as ltJEXtQIKlS for ward.ina slightly convex line; The left side of the head is cut awayobliquely from'the edge 7 forminoa -faee j and the supporfing-face j isinclined v upwardly, with relation .to the arm .11, from the edge ii sothat the righohand endofthe rear edge j" is nmterially higher than theleft, the face sloping downwardlylfrom the v right-hand rear portion ofthe head, to the edge 7 the extentof said inclination being such'thatwhen the side of the heel is supported on said face y" the heel will beheld in the desired position to'perform the scourmg operation. It may bestated in this connection that -it is desirable that the abrading action'on the heel shall be, as nearly as possible, in the-direction of thejoints be tween the lifts. The faces 3' and j meet with the rear side ofthe rest in a vertex 3' and, as these faces are arranged at acuteangles, said vertex may be termed, for convenience, a projection.

In-practice the restis adjusted so that its rear edge 3'" is a shortdistance from and approximately parallel to the abrading face 'of thewheel and its supporting-face is a short distance, varying according toconditions, below the level of the center of the I wheel and at such anangle with relation to the adjacent surface of the wheel that itinclines downwardly therefrom. Said rest is also adjusted transverselyof the face of the heel tosuch a position that the end of the projectionis at a distance from the edge of the wheel face opposite the restsupport equal to the thickness of the heelseat or sole to which the heelis attached,-

or the distance from the base of the heel to the upper, see Figs. 2, 3,4 and ,In using the .device, after the rest has been properly adjusted,the back of the heel supported on the face i of the rest, with 1 theshoe upper in front of the rest as shown,

, zontal position of Fig. 4 and below the level of the upper face 9',the edge of 'its shank would engage said face if the edge j extendedperpendicularly to the rear edge y'" Jon account of the pitch of theback side of the heel, which makesit necessary to hold the forepart ofthe shoe in the right, but,

as the edge 7' and face 7' extending'down ward therefrom, extendobliquely to' the right from the rear edge vjQ-the edge of the shank ofthe shoe will engage said oblique edge and be'forced to the left, as theforepart is swung down, so that the end of vertex will bear on the shankclose to the breast of the heel. As the distance from the end of vertex7' to the adjacent edge of the abrading face is equal to the thicknessof the heel-seat, said vertex will act as a guard permitting theheel-seat to be scoured.

. close to the-upper, and preventing actual engagement of the upper withthe wheel.

' As the shoe forepart is sw'ungdown itwil-l also be swung beneath therest, as indicated'in Fig. 2, the operator being permitted to hold theshoe at any necessary angle according tothe pitch of the heel and alsoto cause the scouring wheel to act on the heel approximately in thedirection of the edges 'ofthe lifts. The edge 7' face j and the vertex jall have practically the same function, which is to act asshank-engaging portions for pressing the shoe laterally and for holdingthe upper out of contact with the wheel, and, as said edge and vertexare boundaries of the face j they may be considered as one element.

The rest is so adjusted that its height and the angular relation of itsupper surface j to the wheel is such thatwhen the forepart of the shoeis swung downward and rearward until the breast of the heel rests evenlyon the surface 7', beyond which position the shoe cannot be so readilyswung, the portion of the upper in front of the shank will be held outof contact with the wheel, as shown in the position of Fig. ,1, so thatdamage to this portion of the shoe, which might otherwise be caused, isprevented. When the shoe is swung to this position, the side of the heelwill have become scoured up to the breastand the operation will befinished. The handling of the shoe in performing the scouring operationis thus not only not interfered with, as the shoe may be moved to allnecessary positions while supported on the rest, but accidental damageof the shoe is prevented, and, as a firm rest for the heel is provided,ridges will not be formed in the heel but it will be more smoothly andrapidly finished, with less exertion on the part of the operator than ifthe device were not employed.

I claim 1. In a heel-scouring machine having a scouring-wheel providedwith a' peripheral abrading-face', a support at one side of said wheel,a heel-rest mounted on said support and having a shank-engaging portionextending to a point at a distance from the edge of said face oppositeto said support corresponding th the thickness of the sole of the shoe,said portion having a heel-supporting face on its upper side and ashank- 'engaging edge extending from its end transversely of andobliquely from said abradingface, and being recessed beneath saidsupporting face from said edge as and for the ,purpose set forth.

2. In a heel-scouring machine having a scouring-wheel provided with aperipheral:
